AMENDMENT I:  THE PURPOSE OF AMENDMENT I IS TO ADDRESS A FEW VENDOR QUESTIONS THAT HAVE BEEN SUBMITTED.

QUESTION:  THE LIST OF CHEMICALS IS VERY HARD TO UNDERSTAND, CAN YOU PROVIDE A LIST IN A PDF OR WORD VERSION?   

ANSWER:  PDF VERSIONS HAVE NOW BEEN ATTACHED VIA THIS AMENDMENT

QUESTION:CAN YOU CLARIFY WHAT IS EXPECTED FROM "BOTH" AND "TANDEM ONLY" CHEMICAL LISTS?  WILL THE CHEMICALS NEED TO BE SPLIT FILLED??

ANSWER:  YES, THE PACKAGING AND DELIVERY SHALL BE DIVIDED INTO TWO GROUPS (BOTH, TANDEM ONLY).  NIST WILL BE USING THEM FOR DIFFERENT PURPOSES AND DO NOT WANT THE CHEMICALS TO BE MIXED TOGETHER.

QUESTION:  ARE THERE CAS#'S OR VIEWABLE STRUCTURES ASSOCIATED WITH EACH COMPOUND?

ANSWER: NIST PROVIDED THE INCHLKEY AND SMILES IDENTIFIERS IN THE CHEMICAL LIST. THESE ARE DIRECTLY DERIVED FROM THE CHEMICAL STRUCTURE.  WE DO NOT SUPPLY CAS NUMBERS BECAUSE THEY ARE OFTEN NOT AVAILABLE AND NOT ACCURATE.  THERE IS NO VIEWABLE STRUCTURE FILE.

ALL OTHER TERMS AND CONDITIONS REMAIN UNCHANGED.
