4First-aid measures

First Aid Measures

Inhalation: Move the person to fresh air and keep comfortable for breathing. If breathing is difficult or symptoms persist, call a POISON CENTER or doctor.
Skin: Take off contaminated clothing. Wash the skin with plenty of soap and water. If irritation or a rash develops, get medical advice.
Eyes: Rinse cautiously with water for several minutes. Remove contact lenses if present and easy to do; continue rinsing. If eye irritation persists, get medical advice.
Ingestion: Rinse mouth. Do not induce vomiting. Call a POISON CENTER or doctor if you feel unwell.

Most Important Symptoms And Effects

No specific symptoms are known. Pharmacologically active material: systemic effects consistent with its mechanism of action are possible after accidental injection, ingestion or absorption.

Likely Routes Of Exposure

Inhalation of dust, skin and eye contact when the vial is opened or the powder is weighed; ingestion through contaminated hands; accidental injection when reconstituted solutions are drawn into syringes.

5Fire-fighting measures

Fire Fighting Information: Combustible organic solid; finely divided powder may form dust clouds. Not flammable in the quantities supplied.

6Accidental release measures

Spill And Clean Up Procedures: Avoid dust formation. Dampen spilled powder with water, wipe up with absorbent material, place in a sealed container for disposal and clean the area with water and detergent.

7Handling and storage

Safe Handling: Open vials only in a clean area. Avoid generating or inhaling dust; weigh or reconstitute inside a ventilated enclosure when the full contents are handled as a dry powder. Reconstitute by adding diluent slowly to the vial wall; do not shake. Wash hands after handling.
Safe Storage: Store the sealed vial at the temperature stated in Section 9 (typically −20 °C for peptides, 2–8 °C for proteins), desiccated and protected from light. Allow the vial to reach room temperature before opening to avoid condensation. Reconstituted solutions: 2–8 °C, protected from light; use within the period established by your laboratory.
Storage Temperature: −20 °C (sealed vial), desiccated and protected from light; 2–8 °C acceptable for short periods
Incompatible Materials: Strong oxidizing agents; strong acids/bases.

8Exposure controls / personal protection

Occupational Exposure Limits: No data available.
Exposure Controls And PPE: No data available.

9Physical and chemical properties

Physical State

Solid

Appearance

White to off-white lyophilized powder

Properties

Odor: Expected odorless/characteristic (no SDS)
Ph: Not applicable (solid); aqueous solutions typically pH 4–7
Melting: Undetermined / not applicable (PEG conjugate, amorphous)
Boiling: Not applicable
Flash: Not applicable (non-flammable solid); combustible organic material
Vapour: Negligible (solid)
Density: No data available (bulk density of lyophilized cake is low)
Solubility: Expected water soluble (PEGylation increases aqueous solubility; the core E-domain 24-mer is water soluble)
Logp: Not applicable (polydisperse conjugate)
Decomp: No data available; peptides decompose above about 200 °C
Other: Core peptide = IGF-1Ec E-domain 24-mer (YQPPSTNKNTKSQRRKGSTFEERK-NH2 type sequence), C121H200N42O39, MW 2867.2; conjugate carries a polydisperse PEG (nominal 2-5 kDa).

10Stability and reactivity

Stability And Reactivity

Reactivity: No dangerous reactions known (generic). PEG chain can autoxidise slowly to peroxides/aldehydes on long air exposure.
Incompatible: Strong oxidizing agents; strong acids/bases.
Decomposition: Carbon oxides, nitrogen oxides on combustion.
Conditions To Avoid: Heat, moisture, light, repeated freeze-thaw; prolonged air exposure of solutions.

Conditions To Avoid

Heat, moisture, light, repeated freeze-thaw; prolonged air exposure of solutions

Incompatible Materials

No data available.

11Toxicological information

Toxicological Information: Acute toxicity, oral
No data available

Acute toxicity, dermal
No data available

Acute toxicity, inhalation
No data available

Skin corrosion/irritation
No data; comparable Cayman peptide SDSs: no irritant effect

Serious eye damage/irritation
No data; comparable Cayman peptide SDSs: no irritating effect

Respiratory or skin sensitisation
No data. Remark: PEG moieties can elicit hypersensitivity (anti-PEG antibodies) in rare individuals.

Germ cell mutagenicity
No data available

Carcinogenicity
Not listed by IARC, NTP, OSHA

Reproductive toxicity
No data available. Growth-factor remark: IGF-1 splice-variant E-domain peptide with mitogenic/growth-factor activity.

STOT, single exposure
No data available

STOT, repeated exposure
No data available

Aspiration hazard
No data available
Routes Of Exposure: Inhalation of dust, skin and eye contact when the vial is opened or the powder is weighed; ingestion through contaminated hands; accidental injection when reconstituted solutions are drawn into syringes.
Symptoms: No specific symptoms are known. Pharmacologically active material: systemic effects consistent with its mechanism of action are possible after accidental injection, ingestion or absorption.

12Ecological information

Ecological Information: No data available. By analogy with Cayman peptide SDSs: water hazard class 1 (self-assessment), slightly hazardous for water; PEG moiety biodegrades slowly.

13Disposal considerations

Disposal Guidance: No data available.

14Transport information

Transport Classification

Note: Not regulated as a dangerous good for transport by road (DOT 49 CFR), air (IATA/ICAO) or sea (IMDG). Not a marine pollutant. Ship refrigerated or frozen as required by Section 7; the coolant (dry ice, UN 1845) is regulated when used.

15Regulatory information

Regulatory Information

Tsca: Not listed (no CAS; new conjugate). R&D exemption applies to research use.
Carcinogen Listings: Not listed by IARC, NTP, OSHA, California Prop 65.
Dea: Not a controlled substance.
Other: Not an approved drug. WADA remark: 'Mechano Growth Factors (MGFs)' are explicitly named in WADA Prohibited List S2.2.3 (growth factors and growth factor modulators) - remark only.

Carcinogen Listings
