2 min

Benzocaine ≥99,9%: an explanation of the name and catalogue data, with guidance on distinguishing variants and checking documentation.

What identifies this product

Benzocaine and ethyl 4-aminobenzoate are names for the same compound. They appear in several OCA listings with different quality claims. The combined article organises the names without equating all batches or variant parameters.

Reference record

How to compare documents

In ethyl 4-aminobenzoate, 4 gives the amino group’s ring position, while “ethyl” refers to the ester portion. Keep chemical identity and purity claims separate when comparing offers. Reagent use does not establish the quality of a finished medical preparation.

Example of an organised record

For Benzocaine ≥99,9%, record the full name, identifier 94-09-7, batch number and document supplying the quality result separately in the laboratory register. Mark an absent measurement as “not stated” instead of filling it with a value from another offer. This allows the next reader to trace the data and recognise which information still requires confirmation.
