FAQ - Technical & Supply Chain
-
Q:
Are Caprylic Acid and Octanoic Acid the same substance?
A: Yes. Both names identify the saturated C8 fatty acid, CAS 124-07-2. It is not capric acid, which is decanoic acid, CAS 334-48-5. Confirm the CAS number and carbon-chain profile because commercial fatty-acid cuts may contain neighboring C6 and C10 homologs. -
Q:
Which batch specifications matter for Caprylic Acid?
A: Agree assay or C8 content, acid value, water, color, iodine value, unsaponifiable matter, residue or ash, and limits for C6, C10 and other homologs. Grade-specific odor or compendial requirements may also apply. Compare the batch COA and chromatographic basis with the intended formulation or process specification. -
Q:
What should be specified for bulk Octanoic Acid packing and handling?
A: State drums, IBCs or tanker, net quantity, container and gasket compatibility, previous-cargo requirements and allowable odor contamination. Because octanoic acid can solidify near cool ambient temperatures, confirm the delivery-temperature and heating arrangement. Check seals, current SDS and the agreed sampling procedure before unloading.
