If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.

How can I determine the shelf life / expiration / retest date of this product?

I understand that benzalkonium chloride consists of substances with methyl groups of 10, 12, 14, 16, and 18. Is the benzalkonium chloride solution enrolled above a mixture of these different benzalkonium chlorides? If so, what is the ratio?
1 answer-
This product consists of the C10, C12, C14, C16, and C18 homologs of benzalkonium chloride, but the exact percentages of these homologs varies slightly from lot to lot. For the percentages of homologs present in a specific batch, please refer to the lot-specific Certificate of Analysis.

How is shipping temperature determined? And how is it related to the product storage temperature?
1 answer-
Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf

Can I get additional information regarding the Ratio Determination for C18? Is this standard appropriate for use in a pharmaceutical quality control laboratory? Ar the CoA results provided acceptable fo use in a pharmaceutical QCC lab related to M300?
1 answer-
Methods of determination are provided on the Certificate of Analysis and are according to current compendial monographs. These secondary standards offer multi-traceability to the USP, EP (PhEur) and BP primary standards, where they are available. This Certified Reference Material (CRM) is produced and certified in accordance with ISO 17034 and ISO/IEC 17025. All information regarding the use of this CRM can be found on the certificate of analysis. The Quality designation of M300 is given according to our M-Clarity™ Program. M300 level products are for products used in applications requiring enhanced change control and quality agreements.
