Hello,

I just wondering if anyone knows where I can order reference standards for

1,3,4-trimethyl-2-methoxy benzene, CAS No.: 21573-36-4, and
1-methyl-2-(1-methylethyl)benzene, CAS No.: 527-84-4.

So far, I only find them from Chinese manufactures.

I appreciate any helps.

Consumer Product Guy,

Thank you very much! I have placed an order for it already. I searched their website also with CAS number, but no result returned. A tech sales rep on the phone finally find it for me.

I am still looking for 1,3,4-trimethyl-2-methoxy benzene, CAS# 21573-36-4.
