2‑Hydroxypentanal CAS 87503-46-6

2‑Hydroxypentanal, also known as 2‑Hydroxyvaleraldehyde, is an α‑hydroxy aldehyde characterized by the presence of both hydroxyl and aldehyde functional groups on a five‑carbon chain. This dual functionality defines its chemical behavior and positions it as a specialty organic intermediate within professional chemical supply chains. 2‑Hydroxypentanal (CAS 87503-46-6) is handled as a defined molecular substance in regulated industrial and research environments, with emphasis on material identification, documentation, and compliance rather than end‑use formulation.
This material is supplied with standardized specifications and complete technical documentation including MSDS, TDS, and COA, supporting compliant handling and traceability.

Application Areas

  1. Pharmaceutical intermediates: Used for synthesizing molecules with biological activity, such as antibiotics, anti-inflammatory drugs, or chiral drugs.
  2. Research on food additives: Exploring their potential as natural flavor enhancers (requiring safety assessment).
  3. Agriculture and pesticides: Aldehyde derivatives may participate in plant signaling or stress response (such as inducing defense mechanisms)

Storage conditions

Storage conditions: It is recommended to store it in a cool, well ventilated environment and seal it to avoid contact with oxidants and acidic substances.
Special requirement: If it is a flammable liquid (similar to tetrahydrofurfurfuryl propionate), it should be stored in an explosion-proof area, away from sources of fire and heat

Safety precautions

Operation protection:
Wear chemical resistant gloves, goggles, and lab coats to avoid direct contact.
Operate in a fume hood to prevent vapor inhalation.
Emergency measures:
Skin contact: Immediately rinse with plenty of water and seek medical attention if necessary.
Inhalation: Transfer to fresh air. If breathing is difficult, oxygen should be administered.
Leakage treatment: When there is a small amount of leakage, use adsorbent materials (such as sand) to collect it, and when there is a large amount of leakage, build a dam and transfer it to a dedicated container.
Fire fighting measures: use dry powder, carbon dioxide or insoluble foam to extinguish the fire and avoid direct impact of water on flammable liquid
