Undecanedioic Acid
Low color • low moisture • aliphatic dicarboxylic acid
CAS
1852‑04‑6
Synonyms
1,11‑Undecanedicarboxylic acid
Formula / MW
C₁₁H₂₀O₄ • 216.28 g/mol
Appearance
white crystalline powder/flakes
Melting range
~112–116 °C
Solubility
sparingly in H₂O; soluble in hot alcohols/acetone
Typical intermediate for high‑performance polyamides (e.g.,
PA6,11) and specialty polyesters/urethanes. Offered in low‑color,
low‑moisture packaging to protect crystallinity and reactivity.

|---|---|---|
| DG classification | Typically non‑DG solid | check route/carrier; keep dry |
| Handling | avoid dust formation | use local exhaust; minimize airborne dust |
| Incompatibilities | strong oxidizers/bases | standard organic acid precautions |
| PPE | gloves, goggles, coat | avoid skin/eye contact; wash after handling |
| Spills/Disposal | sweep/collect dry | dispose per local regs; avoid drain entry |
Always consult the SDS. Store in a cool, dry place. Use moisture‑barrier packaging; reseal promptly after opening.

• Polyamide salt for PA6,11 (hexamethylenediamine + C11
diacid).
• Polyesters/urethanes; epoxy/amine curing formulations. • Specialty intermediates for lubricants, corrosion inhibitors. |
• 25 kg multi‑layer bags (inner liner).
• 500–1,000 kg FIBCs (supersacks) on request. • Custom particle size/low‑color lots available. |
• Keep dry; ambient storage; avoid heat > 40 °C.
• Minimize dust; handle with LEV; use lined tools/hoppers. • Track moisture/color; follow FIFO. |
Share your polymerization route (salt formation vs. direct melt),
moisture/ash limits, and bag vs. FIBC preference in the RFQ so we
can match the right lot and packaging.
