Valganciclovir Hydrochloride impurities and related standards

Valganciclovir Hydrochloride is held here as a working collection of 9 reference materials across 2 CAS numbers. Within the range, the lettered series runs from D to S with 5 letters present. 8 of the entries are impurity-type materials of the parent, 9 are salt or counter-ion variants. 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. Storage behaviour differs across a series like this even when the parent is stable. The N-oxides and the hydroxylated analogues are the ones that drift upward on standing, and a certificate that states storage conditions without saying which degradant was monitored leaves the user unable to tell whether a rise on stability is the material or the handling. Asking for the specific impurity by letter and by structure is faster than asking for a percentage of total related substances, because the second question has no single answer.

Frequently asked

How many Valganciclovir Hydrochloride-related reference standards do you hold?
3 standards are listed on this page as of the latest catalogue build. CAS numbers are published for 3 of them and 3 entries carry a structure drawing. The catalogue is extended as new lots are released.
Can you supply a Valganciclovir Hydrochloride 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 Valganciclovir Hydrochloride 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 Valganciclovir Hydrochloride 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.
