HELP pls
I have a chemical sitting on shelf from long long time(before i started job here)now i tried to update MSDS and couldn't find any by this name.It is supplied by chem supply,can you pls help me what to do?from where i can get new MSDS?will it still be ok to use or......

what is the chemical and how much have you got please?

sorry i forgot to write name its Copper(II)Nitrate Hemipentahydrate(CU(NO3)2 1/2. 5H2O

ITS Almost 300gms

Is the UN Number 1477? If so its Copper II Nitrate. Taken from the CSIS

Hi Shanna
I searched on Chem Watch and found VWR copper(II) nitrate hemi(pentahydrate). UN No 3085. I can't get an SDS from the Chem Supply site.

If you cannot obtain a SDS from the supplier ie the supplier no longer exists or they no longer produce the product, Workcover says it is acceptable to use a SDS for a similar product, or a generic SDS from Chemwatch would suffice.

Thanks for reply.I think they no longer producing it.I got the old SDS from supplier in my folder,which is been issued in 2002.will it be ok to use chemical because there is no expiry date there?

Yes Labbie UN number is 1477

no, its no good if it was written in 2002. All SDS"s have to be replaced every 5 years from date of issue. Issue date is used to calculate expiry date.

Sigma-Aldrich has the SDS for that chemical. It is UN1477. I have an old bottle of copper nitrate that has mostly gone to liquid. I use it when needed for flame tests as it it definitely a concentrated solution.

Thanks Lyn i will look and get a print from Sigma- Aldrich

Don't go straight to the Sigma-Aldrich site. Google the chemical name first then choose Sigma-Aldrich SDS. I tried going straight to the company site and ended up having no joy. Let us know if you had any success.

Hi Folks
The UN No. 1477 is a generic classification for " NITRATES,INORGANIC,N.O.S." and is used for DG transport. Some UN Numbers are specific but many are generic.
If you want a specific identifier for a substance I suggest you use the CAS No. (Chemical Abstracts Service Registry Number) which can be found in section 3 of the SDS. In this case copper (II) nitrate hemipentahydrate is 19004-19-4.
Hope this helps.

SDS copper(ll)nitrate hemipentahydrate. Hope this attachment works. Don't take any notice of the name of the attachment. It is the SDS for your chemical. Revision date is 19.10.2015. You won't need to replace the SDS for another five years. Sorry for the messing around but I have never tried to add an attachment to anything before this.

Well done Lyn, that's great.

Great job Lyn.I am really obliged

I have quite a few old chemicals from the old Gov Stores days.. I use Chemwatch..
