Tolmetin Sodium impurities and related standards

Tolmetin Sodium is held here as a working collection of 147 reference materials across 145 CAS numbers. Within the range, numbered impurities go up to 143. 145 of the entries are impurity-type materials of the parent, 147 are salt or counter-ion variants and 1 carry a deuterium label. 14 entries carry a verified structure drawing, a coverage of 10%; the rest are listed without a structure rather than with an unverified one. 14 of them sit in tier A or B, meaning the data behind the page is complete enough to be indexed and quoted directly, while 133 remain tier C and are kept for search coverage. The lettered series exists because a pharmacopoeial monograph needed to name the impurities it controls, not because the letters follow any chemical order. Two suppliers can both claim coverage of a monograph and still hold different sets, so the comparison that matters is against the letter list in the monograph rather than against a catalogue heading. Co-elution with the parent is the trap in a series this closely related, so the useful certificate data are the retention time under a named method and the relative retention, not a purity figure alone.

Frequently asked

How many Tolmetin Sodium-related reference standards do you hold?
13 standards are listed on this page as of the latest catalogue build. CAS numbers are published for 13 of them and 13 entries carry a structure drawing. The catalogue is extended as new lots are released.
Can you supply a Tolmetin Sodium 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 Tolmetin Sodium 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 Tolmetin Sodium 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.
