Diethylcarbamazine impurities and related standards

Diethylcarbamazine is held here as a working collection of 9 reference materials across 3 CAS numbers. 1 of the entries are impurity-type materials of the parent, 6 are salt or counter-ion variants and 1 carry a deuterium label. 3 entries carry a verified structure drawing, a coverage of 33%; the rest are listed without a structure rather than with an unverified one. 3 of them sit in tier A or B, meaning the data behind the page is complete enough to be indexed and quoted directly, while 6 remain tier C and are kept for search coverage. Materials of this kind are used as building blocks, reagents and analytical references rather than as degradants of one drug, so the questions that decide usability are different: batch-to-batch consistency, the water and counter-ion content the certificate has to state, and whether the structure on the page was verified rather than copied from a name. These are the materials most often bought on price alone, and the two places that shows up later are residual solvent and trace metal content, neither of which is visible in a chromatographic purity figure.

Frequently asked

How many Diethylcarbamazine-related reference standards do you hold?
4 standards are listed on this page as of the latest catalogue build. CAS numbers are published for 4 of them and 4 entries carry a structure drawing. The catalogue is extended as new lots are released.
Can you supply a Diethylcarbamazine impurity that is not listed here?
Yes. Non-compendial impurities can be quoted from a structure — a CAS number is not required. Send the structure, a SMILES string or the parent drug substance with your enquiry and we will come back with availability.
What documentation is supplied with Diethylcarbamazine impurities?
Every lot ships with its own certificate of analysis. The certificate records the catalogue number, the batch number, the tests performed, the specification applied and the result obtained for that lot. A safety data sheet is supplied with the shipment.
Do you publish prices or a lead time for Diethylcarbamazine impurities?
No price list is published: quotations are prepared per enquiry, because availability and packing depend on the lot and the quantity you need. Send the catalogue number and the quantity and a technical contact will answer with availability and a quotation.
