Phytonadione impurities and related standards

Phytonadione is held here as a working collection of 47 reference materials across 8 CAS numbers. Within the range, numbered impurities go up to 42. 31 of the entries are impurity-type materials of the parent, 4 carry a deuterium label. 7 entries carry a verified structure drawing, a coverage of 15%; the rest are listed without a structure rather than with an unverified one. 7 of them sit in tier A or B, meaning the data behind the page is complete enough to be indexed and quoted directly, while 40 remain tier C and are kept for search coverage. The practical difficulty with a series of this size is not obtaining any one impurity but demonstrating that the set is complete. A validation package normally needs the specified impurities plus the unspecified ones above the reporting threshold, and the second group is where a catalogue either holds the material or does not. Where the impurity is a chiral species, the enantiomeric ratio belongs on the specification alongside the chemical purity, because an achiral method reports the two together as one peak.

Frequently asked

How many Phytonadione-related reference standards do you hold?
11 standards are listed on this page as of the latest catalogue build. CAS numbers are published for 11 of them and 11 entries carry a structure drawing. The catalogue is extended as new lots are released.
Can you supply a Phytonadione 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 Phytonadione 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 Phytonadione 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.
